WPB: "Experimental Investigation of mechanism of insitu gel polymer containing paramagnetic nanoparticles for water shut-off in oil fields in presence of magnetic field and simulation of the system using computational fluid dynamics (CFD) technique" is the Ph.D. dissertation of Behnam Sabzi Dizajikan, conducted under the supervision of Arezou Jafari and supported by the Iran National Science Foundation (INSF).
Behnam Sabzi Dizajikan explained this project: "Currently, the economic lifespan of many petroleum and gas production wells has been reduced due to excessive water production and the associated costs. These costs include extraction, separation, and disposal. Additionally, the produced excess water increases the risk of formation damage, corrosion rates, and the tendency to form stable emulsions."
He continued: "Besides these issues, the improper water-to-gas ratio also increases the likelihood of hydrate formation. Therefore, adopting strategies to reduce excessive water production is essential."
The researcher further elaborated: "Implementing processes in reservoirs and wells to reduce unwanted water production while simultaneously enhancing hydrocarbon recovery can meet a wide range of environmental and economic objectives."
He described a potential solution to these challenges: "Blocking the pathways and fractures with high permeability that allow water to flow into petroleum production wells is an effective strategy—provided that petroleum flow paths remain unobstructed. To achieve this, smart polymer gels that swell in response to water but shrink in the presence of petroleum are a suitable option. However, they come with challenges such as poor performance in low-temperature reservoirs or lack of control, which can lead to blocking petroleum production pathways."
Quoting the Iran National Science Foundation (INSF), thisresearcher concluded: "To optimize and improve the performance of these gels, we explored the use of magnetic nanoparticles embedded within the polymer gel structure and applied a magnetic field to precisely control the gelation process. The outcome of this research was the development of a magnetic gel with controllable gelation at the desired location and time, along with the ability to be degraded when necessary. Fortunately, the project's objectives were successfully achieved."
